Description

1769-OF2 Allen-Bradley Analog Output Module is intended to be mounted on a well-grounded mounting surface, like a metal panel. No additional grounding connection is required from the module's mounting tab or DIN rail (if used) unless the mounting surface can be grounded. In the down position, 24V DC power is drawn from the external power supply. External power supply to the module through the terminal of the module Block External power supply must be rated Class 2 with a minimum range of 20.4 to 26.4V dc and 120 mA minimum 24V dc.

Advantage

1. The advantages of using replaceable input and output cards instead of the exclusive PLC design are numerous.
2. First, and most obviously, the fact that individual input and output cards can be easily replaced in case of failure without complete PLC replacement.

Disadvantage

• PLC has a specific circuit operation.
• Manufacturers of PLCs only offer closed-loop architectures.
• PLC is the new technology that requires training.
• There is a limitation of PLC working under high temperature, vibration conditions.
